BP cuts short another US GoM rig contract

Ensco Plc. (“Ensco”) has announced that it has received an early notice of termination for the ENSCO DS-4, a drillship operating in the US Gulf of Mexico (“GoM”) for BP. Under the terms of the termination notice, the estimated effective date of contract termination is July 2015, following completion of the BP’s current well. Under the terms of the early termination notice, BP is required to make a lump sum payment of USD160 million to cover the period from estimated termination through to the originally contracted expiration date of 15th July 2016. Ensco will market the ENSCO DS-4 following the completion of the contract in July 2015. This early termination notice follows BP’s similar decision to terminate the contract for Seadrill’s West Sirius semisubmersible drilling rig. Both units are currently operating in the US GoM, where BP must have decided that it is oversupplied in terms of drilling rig capacity.

BP drills duster in Gulf of Mexico

Noble Energy, Inc. (Noble) today announced that the Bright exploration well in the deepwater Gulf of Mexico reached the targeted Upper and Middle Miocene objectives and did not encounter hydrocarbons. Drilled to a total depth of 13,500 feet on Atwater Valley 362, the well has now been plugged and abandoned. Full well assessment and the integration of drilling results into the Company's geologic models is ongoing to determine forward exploration plans on the recently acquired Atwater Valley acreage. Susan Cunningham, Senior Vice President, Gulf of Mexico, West Africa, and Frontier, said, "While we are disappointed with the results of the Bright well, we remain extremely encouraged by the recent success of our exploration program in the Gulf. We look forward to results at our Katmai and Dantzler exploration wells later this month." BP Exploration & Production Inc. operated the well with 50 percent working interest and Noble Energy had the remaining 50 percent. The Company expects third quarter 2014 exploration expense to remain within guidance of USD150 to USD250 million.
